Substitute Part Grouping Explanation

Substitution of the TE Connectivity 1676418-5 is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part RN73C2A6K81BTDF maintains identical specifications for resistance value, tolerance, power rating, composition type, package form factor, temperature coefficient, and operating temperature range. Both parts are manufactured by TE Connectivity Passive Product within the RN73 series and share the same 0805 (2012 Metric) package designation with identical physical dimensions and termination configuration.

The primary distinction between the main part and the substitute lies in packaging format. The main part number 1676418-5 is supplied in standard packaging, while RN73C2A6K81BTDF is supplied in Tape & Reel (TR) format. This packaging difference does not affect electrical or mechanical compatibility and permits substitution based on procurement and assembly requirements.

Key Parameters for Substitution:

• Resistance: 6.81 kOhms
• Tolerance: ±0.1%
• Power Rating: 0.1W (1/10W)
• Composition: Thin Film
• Package / Case: 0805 (2012 Metric)
• Temperature Coefficient: ±10ppm/°C
• Operating Temperature Range: -55°C to 155°C

Parameter Comparison

Engineering Selection Recommendations

Both the TE Connectivity 1676418-5 and RN73C2A6K81BTDF are Active status products manufactured by TE Connectivity Passive Product. The substitute part RN73C2A6K81BTDF provides ROHS3 compliance and REACH Unaffected status, offering enhanced regulatory alignment compared to the main part. Selection between these components should be based on packaging requirements and regulatory compliance needs for the end application.

For applications requiring Tape & Reel packaging format and ROHS3 compliance, the RN73C2A6K81BTDF substitute is the appropriate selection. For applications with standard packaging requirements, the 1676418-5 main part remains suitable. Both parts deliver identical electrical performance and mechanical compatibility within the 0805 (2012 Metric) form factor.

Frequently Asked Questions (FAQ)

Q: Can RN73C2A6K81BTDF be used as a direct replacement for 1676418-5?

A: Yes. Both parts are electrically and mechanically equivalent. They share identical resistance values (6.81 kOhms), tolerance (±0.1%), power rating (0.1W), composition (thin film), package form factor (0805), temperature coefficient (±10ppm/°C), and operating temperature range (-55°C to 155°C). The primary difference is packaging format: RN73C2A6K81BTDF is supplied in Tape & Reel format while 1676418-5 uses standard packaging.

Q: What is the significance of the packaging difference between these parts?

A: Packaging format affects procurement and assembly processes. Tape & Reel (TR) packaging is optimized for automated pick-and-place assembly operations and high-volume production runs. Standard packaging is suitable for manual assembly or lower-volume applications. The electrical and mechanical specifications remain identical regardless of packaging format.

Q: Are there compliance differences between the main part and substitute?

A: Yes. The substitute part RN73C2A6K81BTDF carries ROHS3 compliance and REACH Unaffected status. The main part 1676418-5 lists RoHS status as Not applicable and REACH status as Vendor Undefined. Applications requiring regulatory compliance with ROHS3 or REACH standards should utilize the RN73C2A6K81BTDF substitute.

Q: Do these parts have identical physical dimensions?

A: Yes. Both parts conform to the 0805 (2012 Metric) package specification with dimensions of 0.079" L x 0.049" W (2.00mm x 1.25mm) and maximum seated height of 0.026" (0.65mm). They are mechanically interchangeable on printed circuit boards designed for 0805 form factor components.

Q: What is the temperature coefficient specification and why is it important?

A: Both parts have a temperature coefficient of ±10ppm/°C. This specification indicates the resistance value change per degree Celsius across the operating temperature range. The thin film composition of these resistors provides this tight temperature coefficient, making them suitable for precision applications requiring stable resistance values across the -55°C to 155°C operating range.

Q: Are both parts currently available for procurement?

A: Both parts maintain Active product status. The main part 1676418-5 has 801 pieces in stock, while the substitute RN73C2A6K81BTDF has 5015 pieces in stock. Availability should be confirmed with the supplier for current procurement timelines.
